bitbake: bitbake-diffsigs: break on first dependent task difference

compare_sigfiles() recursively calculates differences on all dependent
tasks with changed hashes. This is done in arbitrary/alphabetical order, and
only the last of those results is returned, while everything else is discarded.

This changes the behavior to instead return the first difference and not calculate
any more, which significantly speeds up diffs of tasks with many dependencies.
